QR Code Security: Protecting Your Customers from Malicious Codes

Understanding QR Code Security Risks

As QR codes have become ubiquitous in our daily lives, they have also attracted the attention of malicious actors. QR code-related security incidents, often called "quishing," are on the rise. This guide explains the risks and provides actionable steps to keep your customers safe.

Common QR Code Threats

1. Malicious Redirects: Attackers create QR codes that link to phishing websites designed to steal login credentials, credit card numbers, or personal information.

2. Malware Downloads: Some malicious QR codes trigger automatic downloads of malware or spyware onto the scanning device.

3. Payment Fraud: Fraudulent QR codes placed over legitimate ones on parking meters, vending machines, or donation boxes redirect payments to attacker accounts.

4. Sticker Overlays: Attackers print their own QR code on a sticker and place it over a legitimate QR code in public spaces.
